To all whom t lmay concern:

Be it known that I, HUGH M. ,OBiuiim a citizen of the United States and a resident of Corona, in the county of ueens, borough of Queens, and State of New York, haveinvented certain new and useful Improvements in Bell Traps, of which the following is a full, clear, and evact description.

Among the .incipal objects which the present invention has in view are: to rovide means for attaching a trap of the c aracter mentioned without calking or Vpacking the joint; to simplify the operation 'of in= stalling the trap and to reduce the time necessary for the operation.

Drawings.

Figure 1 is a vertical' section of a tra and a fragment of the waste` pipe to whicl'i the same is connected;

igure 2 is a top plan view of the same; an

Figure .3 is a vertical section on enlarged scale-of a fragment of the trap showing in lbroken line the raised position of the cover.

Description.

Heretofore the approved practice for inis aior ed for the carrying into. effect of the operation. Also the space below the trap is necessaril 'limited and inconvenient, which inclines t e mechanic to hurry or neglect the operation.

The abovefmentioned dilieulties are avoided when using parts for installing the trap constructed and arranged in accordance with the present invention. The nipple 8, which extends below the tra 15, inside theN bell 16 thereof, is prrovide with a screw threaded section 9. he nipple 8 isshort as compared with former constructions, andv provided for the use of a short fitting pi e 10, having an end 11 threaded to receive t e coupling 12. The threaded section'9 of the nipple 8 corresp'cnds with the thread of the coupling 12. e coupling l2 is screwed tight on the pi 10 to fixed relationl creto.

ave a substantially with the coupling 12, it is Vnow ossib vlive The lower end of the pipe 10 is seated in the socket 13, formed on the end of the waste pipe 14. The joint between the pipe 10 and waste pipe 14 in the Asocket 13 is calkedwith the lead 18, which is poured into the 'oint while hot.

T e bell trap 15 is of the usual construction having a cover 19, which is hinged by means of a pin 20 to the supporting flange 21 of the cup'15. i An inverted bell 16 is secured means of a screw 22 and nut 23 thereof, as shown best in Figure 1 of the drawings. When installing a bell trap constructed in accordance with the herein disclosed invention, the'short fitting ipe 10 is measured and cut to measure with reference to the relation of the bell trap 15, when in its service position, and a waste pipe 14. The fitting pipe 10 is then attached-to the waste pipe 14 by'means of the calking 18. The pipe 10 having been previously eiuipped e to receive the; threaded section 9, o the nipple 8, which is screwed down into the coupling 12, until the yflange 21 rests in position to be flush with the floor 17 when the same is raised above the said flange.

Itis obvious that as the operation of seating the-pipe 10 in the socket 13 of the waste pipe 14 is notv obstructed, a workmanlike operation may o vious that the bell trap 15 may be quickly and readily adjusted to its service vposition with reference' to the floor 17, for which it may be raised or lowered on the threads of the coupling 12 and section 9. v

It'w'ill also beunderstood that in the event of accident tothe trap or parts connected therewith, it may be readil removed from service byunscrewing the nipple 8 from the coupling 12,v an operation which may be quickly and easily performed.

The combination of a bell trap having a' depending integral externall threaded denipple, a waste ipe a ined with said iipp e and having a ub or socket at lits upper end, a short ipe section having its lower end rigidl an permanently calked in said socket and aving the upper end thereof (provided withan external screw thread, an an internally threaded pipe couplin sleeve having the nipple and the upper end of the short pipe section threaded into the ends thereof.
